Talk:Cathode

hi, just clearing up some basic concepts

anodes and cathodes are defined by their relationship between the source of the electrical energy, and the thing which receives that electrical energy. on the source of the electrical energy, the anode negative, while the cathode is positive,and on the thing which receives electrical energy the polarities are opposite. hence a discharging cell has a negative terminal anode but a cell being recharged or undergoing electrolysis has a positive terminal anode instead is this correct?

The part of the cathode ray tube is incorrect. The electrons flow off of the negnative terminal: http://electronics.howstuffworks.com/tv3.htm
